Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.

There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community
https://mapcomplete.org is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
I don't like that google selectively chooses to show certain businesses over others.
But at the same time the lower screenshot is just pure information overload, it has way too much going on for a casual map to use while walking around and that sort of thing.
100% paid placements. I started looking for an alternative to Google Maps once they started putting POIs disguised as ads.
